Ha, I loved TVRs well before that movie came out! In fact, I loved TVR before I knew they made cars after the 60s! I like the original Griffiths, and I was surprised when I was playing Gran Turismo and it had TVR in it! They had a Griffith and I said, that's not a Griffith! Then I read the little history bio thing, and got on the internet
To cut a long story short, sell your Jag, JSB88, there is no excuse to own a Jag when you don't own a Cerbera... unless you're concerned with the ride, in which case, WTF, you own a 340! Why would you care about ride quality?
