Sounds like you have found your next car Rex , in stock guise these are fantastic machines but not what i would call "challenging to drive on the limit " , in fact the unmodded 3 ZMRs i had all flattered me to the point i felt like a great driver ( which i doubt i am

) at 3 digit speed in & out of bends they just do it all so easily

& that's not just me :| on our many euro trips with 7/8 other similar cars we all experienced the same feeling that the machine far outweighed our capabilities .
Now throw in the supercharger , rollcage & brakes & i think that car will be something to be wary of with the right foot down :evil:
As for value ? Imagine the car returned to stock on 63k & minted 8) that would be worth around £13k/£14k max
Right now the ask is £19995 (it was initially closer to £25k i believe) which in my eyes looks great value for someone like yourself as its got circa £12k /£14k of mods & extras done that you don't have to .
If you bagged that around £18750/£19250 id actually think youd bought somewhat of a bargain if you multiplied the sum of its parts
As i said above , its only going to appeal to a certain buyer & you appear to be that buyer .
I would go into it as any other S54 ZM , check the history , listen hard when starting cold & ticking over , same when warm .
Regards the technical points of the cars handling , not my department but a few members have knowledge & experience that i'm sure they will be happy to share (Tomk & BMWZ4MC )
Happy hunting , be great if the car does land on the forum
