My John experiences: In 04 and 05, worked for a Auto Shop Program for At Risk Youth where we bought a speedster and a HumVee....they arrived with all sorts of issues.
1)SPEEDSTER Former boss bought a new JPS drove 2900 miles to get it ,
he sat in a hotel and that shop all week while it was worked on and boss had
to return 2 weeks later to get it.
a)Hard top was poorly fit and off by 1.25 "at the right windshield area,
we had to repair that and repaint
b)Type IV motor was so far out of adjustment
c) A/C compressor bracket was a chrome aftermarket GM generator bracket
that provided little support for the compressor and would throw a belt daily.
d)Wiring was a rats nest nightmare, connections loose or pulled out.
e)Rear body to chassis mount bolts loose, shock bolts loose
f) Oil leaks & exhaust leaks and clearance issues.
2)HUMVEE A 3/4 size Hummer replica
a) driver's door had clearance issues with roll bar and wouldn't close correctly
b) Wiring was again a nightmare and rats nest with loose connections, pulled tight,
headlights would not go off unless battery disconnected, E brake handle
was swinging in the breeze, ran poorly with out of adjustment
i.e.clutch slipping & oil leaks, steering wheel and switches were loose.
c) Paint had issues to include a quarter panel that had what appeared to be a
carton set up against it while the paint was still wet and he let it go out the
door like that.
Phone calls if answered went w/o much help and a "Oh you can fix that
yourself" attitude.
Sad that this all continues in one form or another especially if the
Buyer resides a distance from Calif.
Little if any test drive time by builder and poor quality control
There was Bill's famous engine seal trim kit that was trimmed wood grain aluminum siding, followed by the luggage rack I won in a raffle,when it did arrive it had been previously damaged / bent and repaired with a file and emery paper and...went to bat on behalf of more than one owner to get parts that were not shipped.
To be fair, recently,after seeing John Heckman's coupe the quality and workmanship has improved.
