Twin exhausts suggest a 260, but i can't see the badge.
Just checked the database, there are 4 LeMans Green 53 plate Mk1 260s, they are all tourers. So not them.
There's one in Biomorphic (just in case it's a poor photo) reg: BC53 DZT, so not that one either.
So, a 190 with a trick exhaust maybe? Looks like a nice car though, i've a soft spot for LeMans Green
One of only 3 ZT 190s made in Biomorphic with duplex exhausts courtesy of Zero exhausts Ashford Kent.Chucking the reg into a search brings up a 2.5 so a 190.
