I dunno about "that other program of Amazon", sorry But I do quite like Car SOS, with the following personal (I stress personal) caveats. IF I was the producer (a big if I know) I would do away with/change the following:
1. Tim Shaw (completely) - NOT at all funny IMO, just a complete ar-e, and I do NOT for one minute believe that all those suppliers he so "successfully" cons are as naïve as shown;
2. More from Fuzz Townsend, AND introduce the rest of the guys (apart from the very occasional word from "Phil" the other don't get a look in, even though I BET they do the lion's share of all the work!). (BTW, good to see a couple of younger faces in that garage recently - could he/they be apprentices?);
3. Completely do away with the entirely self-imposed and completely artificial deadline - it does NOT add drama, just irritation (IMO);
4. Let Fuzz do a LITTLE more explanation, both in his own shop and at other places - it IS getting a little better IMO, e.g. that piece a while ago about "stitching" a cracked cylinder block, but as said in a previous post in a similar vein, I'm not expecting a complete half hour tutorial;
5. Cut down on the personal sob stories.
I strongly suspect that as a TV critic I'm pretty useless and not at all "the average viewer".
Edit for P.S. I haven't watched Top Gear for a long time, so dunno the answer to the OP's Q, sorry.
