16V every time if you can find one, however if you can;t don't feel you're getting a bum deal with the 8v. It's still pretty rapid (as long as you arent trying to accelerate up a steep hill in 5th from 40mph), just needs a damn good thraping for serious progress. And they can always be modded to pretty close to 16v power with a new ECU, air filter and exhaust. And it's still a Golf GTi

I've run my 8v for 18 months now and have only needed to replace the water pump and the tyres. I'm fairly sure a trip to Switzerland in winter took care of the water pump (Sitting in a train station car park all day in -12 to -15 temperatures can't do anything with water in it any good tbh). Haven't noticed any cutting out problems (well, it did it once whilse maneuvering) and the ABS light, whilst tempremental in very cold or wet weather, generally stays off.
And all this for a car with 98K miles on the clock.
So yeah, Golfs are pretty sound.
I'd also venture that the daddy isnt the Mk1 GTi or the VR6. Tis clearly the R32
