I had a Chimera 500 from new in 98. I loved the car only problem I had was a hot starting issue. They replaced the starter cables with thicker ones under warranty and it never missed a beat after that.
I did about 20K fun miles in 2 years then wrote it off at Castle Combe Quarry corner. Would probably still have it now if I had not.
It was loud, fast (though a lot of that was probably perceived because of the noise) looked amazing and a lot of fun.
People say they handle crap but I disagree, they however do not suffer fools. They have a lot of grip but you have to remember they are a light car with a fair amount of power (and torque at low revs)
I have thought about getting another. Older cars do suffer from rusty out riggers on the chassis and a service did seem to really mean bolting the thing back together every 6K miles.
However the Rover V8 powered cars were pretty reliable and very simple to fix and maintain if you can wield a spanner.
The TVR powered engines the AJP V8 cars were pretty good and 4.5L engines make a lot of power. They were not built to a price and on the whole were good.
The initial six cylinder engines however were problematic they would eat cam followers and thus cam shafts. This was mainly due to the fact they tried to make the engine cheaper to manufactures. However by an engine that has be re-built by a specialist and you would be good to go and a lot of them offer engine warranties.
If I had cash left after a Aprilia RSV4 Factory and a 911 GT3 I would have a last of the line Sagaris in the garage
