I have a 80th anniversary TF in green. The colour combo suits the car very well, and the green is really good when polished up. It's pearlescent so it shines brilliantly and is a bit different to the standard BRG. The interior is never going to be fantastic, but I think the 80th is the best of the bunch. The colour isn't as bright as it looks.
I'm under no false pretenses that the anniversary model is going to magically hold its value, beacuse it won't really. It does have the advantages of having all the bells and whistles.
My only regret is that insurance was prohibitively expensive on the 160. The 135 provides ample fun on B roads. Fun to drive, and with no roof on you won't really care!
Don't let anyone put you off, they're a bit of fun, you'll always be able to buy a better car what ever you buy. I could never get along with the looks of the MX5, so I didn't really consider it. Let's face it, if you're buying a 2 seat convertible, looks are quite important too.
HGF, touch wood I've not had it after nearly 38000 miles. Check the coolant, I wouldn't be surprised if it goes eventually, but that's life. Don't thrash it from cold.
Don't forget to wave!
EDIT: Missed the update, congratulations! How are you finding it? 6.5k isn't bad considering you got a new soft top thrown in, they come close to £500 iirc.
