Unfortunately most people won't be able to see past the damage I'm afraid. Whilst it shouldn't be a difficult repair it would run into several hundred Euros for a guy who doesn't do bodywork himself, and there's the added probability that the paint won't match
For what it's worth (and this is just my opinion bearing in mind all four of my 131s are Series 1
) -
1) this car is not UK/Eire MoT'd or UK/Eire registered
2) it is a 1300, so quite underpowered (although I know they are spirited little engines
)
3) it is a series 1 (which means that there is a more limited market as most people want series 2 and 3 Twin Cams)
4) it has already had floor repairs - what standard and quality? Will it need more?
5) it is not a Racing/Sport!
If it was closer to me then I'd go and view it as I'm a Series 1 fan, but unfortunately I am in a very small minority.
