I've seen someone modify a R129 SL500 into a R230 SL500, look 99% identical, even with the retractable metal roof and 7 speed tip box.
Anyway this guy did a remarkable job, for any average Joe, they wouldn't able to tell the different. But there are some give away, heeheh I thought I point them out.
1. Dials, the SLR Dials are black when switch off, & only the words & numbers lumminate bright white with a bit of light blue when in use.
2. The engine is really messy apart from the engine cover, even then, its still the wrong one, as used the V8 one & not the V12
3. The interior switches are missing.
4. Missing all 10-12 airbags.
5. The rear end is shorter.
But as I said before, this guy has a remarkable workmanship. Hats off for him.
Now who’s going to turn a FTO into a mini Aston Martin ehehehehe
