TVR don't care about 95% of the public. 95% of the public would never buy a car like a TVR no matter what it looked like because it's a weekend car and it has pretty much no practical purpose at all. It's the 5% that may be potential customers TVR wan't, like me (if only I had the money), the Sagaris looks a lot different from the T350, thoes slits are one of the main things that set them apart looks wise, I think TVR did the right thing leaving them there. At the end of the day, they're only closed because it's not good to have mud splashed all over you're windscreen driving a 400Bhp rwd car. If you want them open get the right tools and do it yourself, if you can affrd 50k on a weekend car you can afford to hav the slits cut by someone, it won't improve things for road driving though. Another reason they didn't want to re-design that area was because of all the wind testing, thoes slits even though not open, still have an effect on the aerodynamics, to what extent I don't know, but I do know subtle changes can have quite an effect.
