Cougar SV1 or SV2?

[RandomConflict]

After much deliberation, I've decided to go for a mid motored car to replace my B4 FT. With the release of the newer SV2, many shops are currently selling off the SV1 at reduced rates. Just wondered if there are any real significant differences in the performance of the two cars, or whether the SV1 is just as good to race competitively at regional/national events as the SV2? With the conversion from a B4, I fully understand that tools etc will need replacing, but what about wheels? Will B4 wheels fit ok? Or will I need to replace everything? I was originally debating on a C4.1 conversion, but with many teething problems seen on these forums etc, I think the Schumacher just seems more dialled out of the box. Any info will be greatly appreciated.

Many thanks,

Alex
