I'll throw my 2 cents into the fray.

I have the "cheaper" cockpit cover from Top Notch. I use it all the time (including when the car is in the garage and I'm out of town). It does a great job of keeping dust and other crap out of the car.

I leave the boot cover on my retracted top and taking that thing on and off is a pain in the ass, in my opinion. The cockpit cover takes almost no room in my trunk and I can now install it in about a minute and take it back off in about 30 seconds. I've used it the few horrible times that I have had to leave the car unattended in the sun. It does a great job of keeping the S. Cal. heat out and keeps prying eyes away as well.

I had one of these things for my old Miata and it held up very well.

I highly recommend it.

PS - Jrosen, please do us a favor and stop shouting with the cap locks.

PSS - damned cool Healey, Starbird. Is that yours?

 

If anyone develops a tonneau cover as shown on Starbrd's Healey, I'll purchase one in a flash.
I had one just like the one in the picture for my 1958 XK150 Jag roadster. It was great, as you just drop the driver's half to drive. All the heat (or air conditioning!) stays down around your feet this way. Plus, less filth & sunshine get on the unused side.

Let me know if this ever becomes a reality for the S2000.
