I would definately keep the beemer.
I hated my 1.6 mk2 (loved it as a first car) but had so many problems with the weber carb it just wasnt worth it. Sold mine for £400 in the end. Tbh that mk2 looks like much more of a shed, yeah ok it has more bits (leather, rear lights, mirrors, wheels) than mine did, but it looks crap condition and possibly not very well looked after. I would avoid that at all costs. Drop the price of the bmw a bit and dont take any offers on it and you should easily be able to find a 1.6 if thats what your after or a 1.8 gti which i would think is more sensible. Lots of bargains to be had, but that mk2 looks like it could be more hassle than its worth!
Just my 2c
