I am contenplating a Renault 25 that is for sale. It's a 87 model, auto. For its age the body seems good, but the dash is quite badly cracked from the sun. It appears to have been well looked after mechanically. Its just a bit tired. I have always liked these cars, but don't know if its a wise purchase. Are these cars reliable? (Generally speaking)What should I look out for? How much should I pay? My other car is a R17G so I'm not expecting it to be perfect. I would be grateful for any help.
