Hi Mark, not a bad score for $10.
The Jag appears to be missing a few body parts, which you may be able to find on epay, or, these bodies do show up fairly regularly, and are inexpensive. The chassis is one of the earlier "train motor" chassis', and with some work it can run OK, but, it looks like you have enough parts to make a second aluminum/plastic chassis which will perform much better. Lots of folks produce repro tires, so, that will not be an issue.
The Lotus is a "30" not a "40" and the chassis appears to be in fairly good shape, so, with a bit of work ,should run just fine.......as with the Jag, tires are easy to find.
Keep your eye out for an all brass Strombecker chassis,.....these are by far the best chassis that Strombecker produced.
Cheers
Chris Walker
Attached is a shot of a Strommie Lotus 30 that I did a few years back........It does have the brass chassis, and aftermarket wheels and Lotus "wobbly" wheel inserts, which although I know you don't like yellow ;) , are correct for the car :D
