1990 Audi Questions

[BASSTREB@aol.com]

Hi everyone, 

Been awhile since I have been in sync with this group, however I need some
good advice.

BACKGROUND:
I have a 1990 Audi Coupe Quattro with 108,000 miles.  Black with black
leather.  I really baby this car however its miles are starting to show.

I just spent $1,000 to get ignition wires replaced, rotor resurfaced, oil
filter changed, all fluids changed, tune-up.....and I anticipate spending
another $1,000 to get it in BRAND NEW condition.  

QUESTION:
Based on what I can get for this car right now.....does it make sense to do
this work and have a tip-top Coupe Quattro (I own it outright, no lease or
payments).........or should I sell it now and lease an A4Q for three years
and just give it back afterwards (or buy it at that time if I am in love with
it)???

I would really appreciate any feedback that anyone out there may have.

Thanks,
Harvey
