Grateful for any opinions / advice.

There is a high km 95 945 Turbo with 286,000kms for sale for $5400 in my area.

Here's the situation:

Positive points...
Previous Owner has all the records since new. Items replaced within the last 2 years.
Exhaust, shocks and struts, ball joints and tie rod end, brakes and many other parts.
Regular dino oil changes with Volvo filters. No synthetic.
Leather interior looks great.
Paint is ok, except for under the windshield which is bubbling.
No oil leaks from underneath the engine.
New Rad, water pump (this is what scares me) - read on...

Negative Points
Rad and water pump were replaced due to a leaking water pump which caused the engine to overheat - though apparently not enough to cut out the engine.
The red paint on the engine block is peeling a great deal. This was the first thing I noticed.
Turbo is covered with oil. There are minor leaks around the vale cover.
The lobe on the one camshaft visibile through the oil filler is slightly blackened - normal high mileage or over heating sign?
Check engine light is on and there is a 2-4-1 code - EGR???
Interior door panels are all puckering / peeling at the windows.
Body panel under the windshield (between windshield and hood is bubbling - like There is rust underneath the paint.
Windshield weather stripping is rusting under the rubber.

My concerns:

1. Engine block and logevity. I have read that peeling paint is an indication of overheating? A friend says that it may be just from running hotter due to it being a turbo.
2. Will this need a turbo replacement? No turbo gage in dash to monitor
3. The other issue is the puckering panels - unsightly and costly.
4. Any problems with Halifax assembled cars? Compared to my 95 940 NA built in Sweden, there is a bit of a difference in fit and finish. Mine is better.

The car has relatively high miles, and I am not desparate for another vehicle, but wanted to buy a 95 945 as a hobby car. Is it worth the trouble? Or am I in for long term expenses. Is $5400 Canadian too much? The car has been for sale for 2 months already.

Thanks
