Pics were posted last year when I got it. Hood has been painted blue (I got close enough you have to look to see it's the wrong color) -- I got tired of the yellow and getting teased.
I'd have to say I cannot decide. I really like the 280, espcially since I got the trigger points clean and the mechanical advance working -- it just flies now. However, I'm also rather parsimonious, and the cost of the fuel is killing me. It is fun outrunning the ricer cars! Everyone pulls out to pass me on back roads, I guess I don't drive fast enough for them. I go lightly on the throttle, it REALLY burns fuel if you stick you foot in it a lot.
My 300D is a dream on the highway -- flies along at 80 very nicely, and it goes forever on a tank of fuel (450 miles so far on the last tank, sitting on 3/4 empty,and that includes a trip with several return lines dripping). Similar performance to the 280, but very little of the head-turning power. Believe me, the 280 gets noticed. Less now that the exhaust is quiet, though.... The 300D is a little sluggish in town.
And for really long highway trips, I still like the Volvo the best. The seats allow you to move around more, so I don't get so stiff, and it gets about the same milage (or did, its in the garage for surgery at the moment) as the 300D with somewhat less power. Better back seat room for passengers, too.
Four country road driving, the 220D is the best -- better handling than the 280. The swing axle design gets obvious at high speed on a twisty road.
