Red MK 1
It was one of the suspects cars and drew the attention of Inspector Barnaby.
! Inspector said something like…“I remember when district nurses drove around in Morris Minors” 
I’m sure it was a mk1 car but displaying an 04 plate. Glaring error ruined the whole show for me !
Well I thought I saw the reg start with a letter M or N when I was watching the tv program. If you copy and paste the address below, you can see it’s an N reg 1996 1.8
But here’s a pic of it, I presume on set:
It was definately a MK1 & I was sure the first part of the reg was ML04, I questioned the reg with my other half but he didn’t see it!
I didn’t see this shot during the episode, when I saw the car it was parked to the left of screen, I think by a hedge & facing camera so I could see the frog eye lights, now I’ll have to find a repeat, I’m feeling confused
Maybe it’s on Yous Tubes 
I’m confused too now, as I’m sure I saw an “M” not an “N”, which ties in with what you say. It was definately a MK 1 as I saw it head onwith it’s little side lights and flip-up lights in the down position. I could even make out the old etermal flame badge. The shape of the front was unmistakeable. Plus it’s on the website as being used on Midsomer Murders. I suppose they’d have to change the reg plate for the true owners protection or somethin
My dad has his VW Fastback used in a few TV programmes… it can be quite lucrative.
Not looked on you tube, just tried ITV Player but not on there, shall have to keep hunting
The picture posted is a bit of a red herring as it is from a different episode.
I’ll try to hunt the episode down 
Tis indeed! Found it on You Tube. It’s ML04 VZM

Dorothy, played by Stephanie Cole called it a “flashy little sports car”, trying to make out that she sponges off her parents Later on it was said the car was bought for Megan for £14000 3 years ago.
