That 205 looks nice, but I would negotiate on price if I were you!
The 1.9 is faster in a straight line, but the 1.6 is faster out the twisties due to the different gear box. A lot of people put the 1.6 gearbox into their 1.9s.
I sold my 1.6 for £1450 a couple of months ago, totally mint and original, on a J plate with 68,000 miles.
My ex had a 205 Mi16 race car...........that was just mad and stupidly fast!!! I loved it though.........well, until it nearly killed us!!!
