Hi all, Just signed up to the forum as I'm in the process of looking for a Z3 for my dad but running into a few issues/queries. The background is he's always wanted a small roadster and over the years he's looked at Triumph Spitfires, MGB's, midgets and so on but never taken the plunge. Now he's looking a small project for his retirement and the Z3 seems right. However, we've been to see a few so far without much success. First up was a low mileage end of line 2002 2.2 topaz manual, and on paper it looked good and was well spec'd. However, in reality it was a complete bucket. The bodywork was marked all over, the engine was unloved and in desperate need of a service and I found weird corrosion spots in the engine bay, whereas underneath looked superb. The roof leaked and didn't go down. It needed brakes and wheels refurbed and on the very short test drive it didn't exactly drive well. It wasn't going cheap so walked away although if anyone pays even half of what the sellers looking they're an idiot! The next one we looked at was a low mileage 2001 2.0 in a nice colour combo. However, this was ...... Slow! I'm not sure if there's a problem or if that's just all the 2.0 has to give, but it's miles off were we want the car to be. Maybe we've been spoilt for performance with our other cars, but this was dead. Previously, he'd had a 328i (m52) and a 330Ci (m54) so I think what we really want is one of those engines, but there's not that many about. Anyway, we walked away again, but I can't help thinking that if we could get the car at the right price it could be a nice project car, but what can really be done to improve the performance? I've spent the evening researching engine swaps using a m52b28 or a m54b30 which actually looks pretty straightforward or even stroking the b20 to around 2.6l with a b28/b30 crank and conrods and using m50/m54 manifold for some extra go. But is this mad? The 2.0 hasn't got the BMW LSD either, so that's another expense just to get the performance/handling that the 2.2/ 2.8(?) /3.0 offers as standard. At this stage I'm not sure whether he'll keep the car long term or if it might be a one season thing to scratch an itch so I wouldn't want to burn money. Spending time on various M3 forums, rare colours and low mileage really command a premium when it comes to resale values. Is it the same here with Z3's? Would a top condition Z3 with a rebuilt engine transplant in a nice rare spec be worth more or less than an average condition original 3.0 model? Given the time of year it's hard to tell from looking through the classifieds. Anyway, any advice would be much appreciated and hope to be amongst Z owners soon.
