Buying a 2008 r32 is it a good idea?

I'm looking to trade in my 2009 mini cooper
s clubman. During this time I found a vw r32
the 2008 edition. It has 130k miles but only
had 1 owner. The last owner also did a lot f
work to it. Such work as air bag kit,
performance brakes, k&n cold air intake, just
cleaned motor with all sensors replaced, just
tuned, has custom exhaust guy said it was
2.5k for the exhaust, special air intake
manifold, nice rims and tires, all new interior
and dashboard, very clean and well kept.
They are asking 8,990 for it and with the
trade in going to be 4-5k for the car. My
question is what should I look for before
purchasing it, will this car last awhile if I do
routine maintenance, is this car a good deal?
