Some great replies guys and a lot of different opinions, I love it. I didn't realize that there are so many different types of C70s with so many different mods, it looks like there is a lot more research for me to do just yet. I see that there are so many pros and yet so little amount of cons which is always a good thing when buying a car.
I am going to go out and test drive a few of these and have a look out for some of the point's you guys have made above. I will be back soon with the outcome.
Thanks
EDIT: In terms of pricing what should I be looking at for a 2013 C70. I use this site most of the time
http://www.for-sale.co.uk/volvo-c70 but as you guys will be able to see there is quite a bit of price variation.
