Hello, I am looking for some advice from forum members,

I currently own a 2003 996 with 115,000 miles that I have owned for the last 5 years, I have done all the maintenance myself and am proud to say I have never had to take it to the dealer for a repair I couldn't do myself. Anyways, as I am approaching 50 I wanted to move up to another Porsche either a 997 turbo manual or a 991 manual, I don't think I could afford a 991 turbo. Where I live its hard to find these models and I'll likely have to throw a 500 mile long search to buy one making test drives to compare both models difficult. Could anyone with experience give me some advice? I plan on keeping this one for at least 10 years maybe longer.
