I worked at a RR dealer in the earley 80's, got to drive lots of them. They weigh 6025 lbs (for tax reasons) and perform well for their size. RR didn't dsclose the engine size, they would say it was adiquite. We had an engine apart and it measured about 420 CI. The RR engine is amazing, steel billet pressed together crankshaft with bolt on counterweights, Hemi Heads...bla bla...
then these stupid SU carbs!

Expensive parts, I once had an Ins. adjuster threaten to come down and kick my but for telling him a set of simple hub caps cost $2600.00 plus a $500.00 trip to the paint shop! That was 20 years ago.

I have driven a couple of 600SEL's and they are every bit as nice or nicer than the RR, in my opinion.
