What are you doing about the paddleshifts? Just haven't seen them mentioned.......
I'd take out any negatives though mate. If you can only see a scratch when cleaning the car, don't mention it. I'd change the sentence about the rear tyres, just put that the car will come with two new tyres. You want to sell the car to someone through your ad, you need to make them pick up the phone and call you over any of the other ads. For every point in your ad, I'd list as many benefits for it as possible. The car is having a P3 on Monday but what does that mean for a buyer? They might be thinking "what the hell is a P3??" Assumes buyers know nothing about the car I'd put something along the lines:
" The car is currently being serviced at a Nissan dealership. It is having a full P3 service which is the most expensive and comprehensive service the car will need. This means that the next service will not be needed for another 9k/12 months and that will be a P1 which is the cheapest at around £130 (Or whatever they are nowadays ooop north) therefore no expensive service costs for a few years. The next P3 is not due for another 36k/4yrs!!
This 350z benefits from the fantastic Carbon Cloth seats that grip you brilliantly and do not get uncomfortably hot/cold like leather seats do!
The exhaust system and anti-roll end links have just been replaced this week so no concerns over them, lots of cost free motoring ahead!"
You want to give people the impression that they can buy your car and not have to fork out a penny just after purchasing it.
