It's pretty hard to put a figure on that sort of vehicle...i see on LCOOL it's a 2000 model 105 series, so that's 15 years old now. The klms on the engine is a big plus, but for me a 15 year old vehicle is a big negative also. I considered doing a similar swap to my 105 series (was toying with the idea of different engines to put in), but in the end i'd still have a 13 year old vehicle, so i have decided it's time to go newer all over now. That likely won't put someone off who's specifically looking for that type of vehicle though, they are comfy to drive and the engine is barely run in.
