TY. Tricky, but we got there!

Great grid! Nuked in 52s flat, but some very good connections there and some red herrings which confused me until I sorted a couple other groups out. Thanks for the sport!

Nice and easy straightforward grid.
Learned in a Toledo (showing my age)
10s all round
Thanks for posting

You're not alone Freddgar - my second car was a Triumph Herald

Excellent grid, but sad that I didn’t get full points because the word “aeroplane” wasn’t recognised. “Airplane” is an Americanism. You should at least allow both!

Monsoon is a wind, not a type of rain

(@Jane: Also Plane and Fighter were not recognised.)

superb grid. many crossovers
loved it - well done

Fighters and planes were in the definitions, aeroplane is now included, searching synonyms for monsoon include all the other rain definitions that are on the grid. Either way thanks for the positive comments

... so of course I put Aircraft. Can't win them all! Too young to remember Triumph, but got it resolved . Thx for setting

Funny, I figured Triumph models would be one of the groups, but the only one I knew of was the red herring. Knowing nothing of planes or sportscars, I ended up with only a 3 (1 group, 2 connections). High quality puzzle, but difficult for my knowledge set.
