Hello my name is Charlie and i was wondering if i could have some advice on my '95 mustang gt cobvertible i bought the car used from a mercedes dealer and that it was only a one owner with 16,000miles

I of course tested everything out in the car
and test drove it and listened to the car for
while and i ended up paying 12,000 for the
car because i thought i knew what shape
the car was in well now its 5 months later
and ive put about $8,000 into the car mostly
on the transmission but everything else
under the sun and she still needs work and i
was planning on restoring the car
completely since im going to be a mechanic
anyways i figured why not and the car will
be a classic in about 5-6 years but i would
like to know if any of you think that its a
good idea to fix up the car or sell it and get
another mustang
