What Gives?!?!

[fast70]

A beetle has been put up for sale by a local german resturant owner and I need help to access its estimated value. It is a 1972 Super Beetle and has various mods-
I will try to list most:

-Light metallic green paint (A BMW color bought directly from the plant in Germany)
-Porsche Fuchs- not sure of tire size but I know they are 7-9in
wide fr/rear (fairly new)
-Wide fiberglass fenders
-1776 engine 7000mi on rebuild (electronic ignition,dual 40mm carbs)
-New headliner
-New Beetle antenna and rear brake lights
-Front bumpers with integral signals
-BMW Recarro seats (heat and elec move not hooked up)
-Porsche steering wheel
-Reupholstered rear seat and door panels to match front seats
-Hideaway exhaust
-Lowered suspension and new front struts
-New speedo--goes to 130
-Flat fiberglass dash
-EMPI short shifter with rev lockout

However the car does have some faults:

-Large front end shimmy between 45-50ish
-Trunk not completed
-Paint oxidized in spots
-Passenger window binds
-Latch on passenger window broke
-Emergency light knob broke
-Parking brake does not work
-Will not idle
-Turn signal broke (does not return to off)
-Upholstery on passenger door panel popped off
-Antenna hole left open
-Seats hard to move and electricals not hooked up

Some problems that my friend found:
-Seats uncomfortable and hard to climb out of(partly due to lowering)
-No leg room in backseat due to large front seats
-Car scrapes on speed bumps or dips in the road

Asking price $6,000 US. Unfortunately I do not have that money to give up front right now nor am I looking to. I was just hoping you guys could give me your honest opinion and tell me what you think it is worth.

Sorry for the long post, I am just trying to be as thorough as possible with my description. I will try to get pictures as soon as possible.

Thanks,
