I finally got to try a Super 3 yesterday - courtesy of the lovely team at Morgan Brands Hatch. It was a perfect sunny day, which must have helped, but I really enjoyed the experience. A few reflections to share:
1. the cockpit is tighter than I thought it would be, particularly when getting in and out, but plenty of legroom with the pedal box adjusted to its furthest position (which was very easy to do).
2. the high pitched belt whine is noticeable at first because it's a different noise than you expect, but I found that pretty soon it faded into the background and didn't trouble me at all by the end. I would love to try a chain drive though - has anyone got one or tried one yet?
3. the engine is quite powerful enough, but obviously lacks the aural drama of the S&S 3 wheeler. I'm keen to try a sports exhaust to see if it makes much of a difference. I didn't miss the vibration of the old model - I could imagine taking the Super 3 for a longer drive. 50mph comfortable, 60 mph starts getting to the point where I'd quite like a visor though.
4. the width of the front wheels didn't bother me at all - its very easy to place and no problem on typical English country roads where two cars passing is a little bit of a squeeze.
5. the ride is surprisingly good - nice plump front tyres and decent suspension travel so really quite comfortable - more compliant than my Aero. I didn't sense the rear getting light going over bumpy, rolling roads, which was re-assuring.
6. I'd like a harder brake pedal feel, but the brakes ultimately work fine - and it's not a car for heroic Lotus Elise/MX-5 driving, so I suspect "slow in - fast out" is the better driving style and engine braking is encouraged by the engine characteristics and the great gearbox.
7. smiles, waves and driver road courtesy experienced at every turn!

Next steps - drive an old and a new back-to-back (I'm favouring a Super 3 at the moment), try out a Super 3 with the sports exhaust, and get my wife to come with me to make sure she knows what she's letting me get her into!

Great in the lovely weather we're experiencing to get the Aero out to drive there and back - nothing quite like a torquey V8 with side exhausts!
Happy driving ....
