The steering wheel is on the wrong side, the car is a bit rough around the edges but look at the price.

Cheap as chips.

You can get them cheaper than that if you don't mind it being an S52 240bhp. Same sort if lower as a 3.0 but with all the trimmings.

Maybe but the S52 is a truck engine in comparison (IMO from some minor research over the last few years) with the S50 like the M50 its based on is prone to ignition issues, over heating, premature piston ring wear and general unreliability in comparison. Apparently!

I think we ended up with the better engine until the S54 came along for Europe and the USA

In addition to the larger displacement, the S52 utilizes the following special M components (compared to the M52):
-Ported and polished cylinder head
-Retuned VANOS variable valve timing for greater high-rpm power
-Heavy-duty valve springs
-More finely balanced camshafts
-Valve lifters, springs and spring seats with reduced mass
-Free-flowing intake and exhaust systems

The European-spec powerplant, known as the S50 B32, is a much more exotic unit. Like the S52, it also contains an iron block and aluminum cylinder head with four valves per cylinder. However, with a bore of 86.4mm and a stroke of 91mm, it has a total displacement of 3,201cc. The S50 B32 incorporates the following special features to allow it to produce an impressive 321 hp (DIN) at 7,400rpm and 258 lb/ft of torque at 3,250 rpm:
-Individual throttle plates for each cylinder
-Increased compression ratio to 11.3:1
-Advanced BMW/Siemens MSS50 engine management system able to compute 20 million instructions per second
-Double VANOS continuously variable valve timing on both intake and exhaust strokes
-Lightweight pistons
-Dual-mass flywheel
-Graphite-coated conrods
-Larger inlet valves
-Secondary oil pump pickup
