I'll try to answer what I can with somewhat limited knowledge, although I do own a Team C Jekyll (TR02 chassis) as well as a TC02C chassis.

TM2 is the forward (longitudinal) motor model with carbon chassis / alu bracing etc. Apparently superb on high grip / carpet tracks

TC02C is a more standard mid motor layout (motor in front of rear drive train). The TC02C evo is a slightly longer wheelbase version with a few other fancy bits (big bore shocks vs the small bore on early TC02C etc) . TC02C is a very forgiving chassis and can be set up for more track surfaces. TC02C takes saddles side by side or presumably a shorty pack

TR02 (Jekyll as was) is the rear motor, basic version. Takes a stick pack down the middle. The TC02evo is the higher spec version.

If it were me I would go with TC02C or the TC02C evo as they are better for varying track surface. That said, I have recently switched to Yokomo so am going to be selling my Team C cars, although they served me very well until now

TC (or R) 02 / C / Evo all have a plastic tub chassis, while TM2 uses a sheet of carbon.
All have approx. same front end although the front arms are available in 2 specs which seems to relate to carbon content (i.e. more carbon = more strength, but there is a £2-3 price difference for spares).

Oh, and there is also the Ansmann range to consider - They used to make the Mad Rat (Team C Jekyll) as well as the Mad Monkey (TC02C / Team C Lupuz). Main difference was that Ansmann used green anodised alloy while Team C used silver grey until the TM2 when it all went a bit "tango". All parts are interchangeable

The T2C models were from a few years ago and essentially were the TC02 and TC02C but with big bore shocks / aluminium hop ups / carbon shock towers etc. as far as I can tell. I don't think they were available in Europe (or UK) although I could be wrong?

There you go... Clear as mud!
