Guys I have decided to purchase my 1st Bull. 2014 Gallardo with 4k miles on it. Its a CPO but I have a few questions. I just got the report from the dealer ship on the car. The report states tires @ 60%, Brakes @ 50%, Clutch snap @.7mm Worn. Just wanted to know should I ask them to changed the tires and Brakes. I am planning on using the car at least 3 times a week.

Nice! Tires and brakes for sure but I would be hesitant with such low miles and 'high usage'.

How long does the CPO coverage last?

Definitely ask the dealer to change those things. If they don't, go aftermarket for brake pads.
