I am deciding to possibly buy a 2007 C2S Cabriolet with the following add-ons:

I'm assuming the bumpers are OEM.
GT3 Front Bumper
GT3 Rear Bumper (with the centre exhaust cutout and side vents)
GT3 Style Sport Exhaust w/X51 Headers
*not sure what GT3 Style means, but it did have a centre dual exhaust
H+R Sport Suspension
GIAC Performance Engine Management
Evolution Motorsport V-Flow intake
*possibly one of these Engine Performance Systems ?
Sport Shifter

The non-porsche dealer is claiming $25,000 in upgrades. But who knows. I personally do not like anyone playing around with engine upgrades unless I know it's done from a well known tuning shop.

So, my question is, what do you think these add-on's are worth for a 2007 C2S Cabriolet with 19,500 miles with no warranty ?


I'm trying to think of a fair offer.

 

Pictures, condition and asking would be helpful tho I'm thinking nothing over the $75K range if clean and well put together with the right (i.e., lucky seller) buyer.

 

Found the LINK (in Canadian dollars)

 

Just bought my first 911 - I specifically avoided anything but bone stock. There are just way too many aftermarket parts and eager shops for a noob like me to determine if it was a good part or junk or if the install was done correctly.

 

In my opinion (and I have a lot of Mods on my car), the front and rear bumper are worth about $5K over blue book IF they are truly OEM. They cost more new with paint and install, but they CAN'T include that in the price! If they are fiberglass, I would say it plays to your preference. Would you add them on if they weren't originally on the car? Replica pieces would be worth less than half that of OEM.

I can get a center exhaust conversion done for about $1000 + tips. Not sure what else the car has in exhaust upgrades. If there are mufflers+header+cats...probably worth about $2000-2200 on the used market depending on brand (AWE or Fabspeed for the price listed)

GIAC is about $1000. H&R springs are only about $600-800 installed. Not's not really a "Sport Suspension." Did they add dog bones or sway bars?

All in all....if you LOVE the car as is, the listed mods are worth about $10K (only if bumbers are OEM). If it were me, I would agree to RETAIL blue book with the mods....again only IF you LOVE the car. If they give you the original parts that were removed, then I would pay more.

 

I wouldn't pay anything more than a stock version would sell for unless you were planning on installing all those mods anyway. These types of mods usually add little if any value. Just ask JELLIS. He had most of his removed in order to sell his car, and sold the mods separately. In many cases, the mods take value away from the car. So be careful.
I just looked at the link to the car. I'm always a sucker for a nice looking cab, and that is a nice looking car. But I noticed they claimed "leather interior", but it doesn't have full leather. I know Canadian prices are typically much higher than US, so it is hard to make an assessment. I would expect a non-modified version of that car to go for low to mid 60's in the US. Good luck.

 

Agreed Ken. I plan on removing all my mods once I sell. Although, I have gotten a few offers for my car as is....just not ready to sell yet. To me though, OEM upgrades offer some value.

Did you see the pics of the car? Pretty cool! Cabs with GT3 front and rear bumpers are rare! It's definitely unique.

 

I'll go with the 'if it's OE it's ok group'. If the bumper covers are fiberglass I would consider that a negative. The car does look nice. To me the mods don't add a lot of value. I'd check the value of similar cabs in your area and base an offer on that information.

I took all of the mods off of my previous car with the exception of the factory aero kit prior to trading it. The dealer didn't want the other mods on the car.

Are you getting a PPI with a DME readout?

 

I picked up my 07 C4S in Jan of 2011 for 61k and 18k miles. Cabs get more of a premium. The car looks nice. Check out the shop who did the mods and see what they have for records. You can get the true cost and then offer nothing over the asking price. Start at 70k and see what they say.

Prequalify for the loan so that you show your serious. Nothing worse than going through the process and not get the car...unless your paying cash!!! Then you would be in a great position.

Good luck.

 

I recently purchased a 2007 GT3 with a carbon hood and Vorsteiner wheels. The car was perfect with low miles. I didn't pay a premium for these options which were worth around $8k and negotiated that the OEM hood tires and wheels were included in the deal. At the very least I suggest that your request the original parts as it will make it easier for you to sell down the road.

 

I took the other approach to this. My list of mods includes/included: Techart Front/Sides/Wing/Wheels, K40 & LED Fronts/Tails. I went on ebay and priced everything out, 1K/2K/2K/5K/1.5K/1K. Total upgrades 12.5K, I then found a car with almost everything I wanted (less LED/Front Lip), so I had no problem going a little over KBB. Hell, I could sell my wheels on ebay pretty easily if I wanted to and revert to stock.

What I'm getting at is the MODS are typically not a value-add unless you're going to be doing them yourself anyway. In which case it makes sense. I don't have any engine mods, so I didn't worry about aftermarket shops tinkering.

 

Mods are tailored to an specific audience. If you are that audience, then go for it. Some people may not like it. I would never take into consideration a mod done to a car as part of the deal, unless I wanted that mod to begin with (like in the case of MBENZF1, which I almost ended with his car! LOL!) Custom upholstery and heavy engine modification (turbo or supercharger) is a big no no in my book. Hi end suspension or Tubi exhaust is always welcomed!

Thanks everyone for their replies. Like most of you, I'd rather buy the car stock, or at least have all the stock parts.

As for the GT3 bumpers, I use to have a SY C4S (in my avatar) with the factory aerokit, so i think I would be doing the bumper changes in my next purchase. It's just the headers, exhaust, springs, etc... are things I can't see myself doing. I've put in an offer based on a clean C2S cab with the bumper changes so we'll see what they say.

it's the most unique and sexy cab I've seen in a long time. i'll keep everyone posted.

 

Standard dealer procedure - discount trade value to seller because of mods and then list car at premium to new buyer because of mods. As a seller, I feel extremely fortunate if I recover 50% of the cost of mods, usually though it's significantly less.

 

Mods = zero increase in value.

That being said, mods are specific to the potential buyer and what they're looking for.
