Hi
It is a very nice car and as an ex dealer in BMW's I would be impressed with the condition, although if its helps you may find the following useful:
-The service history is fine, no issues and does not affect the price or desirability as its full bmw and specilaist, which is a must with these cars
-The wheels and springs are specilaist and not standard, you'd actually get a quicker sale and more money to put it to standard and open up the target audience, mods put off alot of general buyers, even those wanting a bit of fun for the summer as its harder to sell on, you'd make extra money selling the mods seperately as they are desirable by enthusiasts.
-Current book price at that mileage is £7650 trade, £8365 private and £9675 dealer, the mods do not add value to book price, only if its has satnav(worth £500 extra), items like heated seats, electric seats, remote roofs dont actually add money to the book price I'm afraid but it does affect deisrability, it makes it harder to sell without these items in my years of experience with bm convertibles.
-Convertibles generally increase on book price by upto 3% on average during May to Oct, although rememeber every car drops in price every month.
-Auto's add about a grand to bmws, the reason is there are less of them, they need less maintenance over its life than a manual and cost £2k+ more at sale, you may think as a drivers car manual is more desirable and you'd be correct, although this doesn't affect the real value I'm afriad so auto's are worth more than manual's.
If you put it to standard you'd get £8350 all day long and probably over a grand for your mods, as it is by the book its not worth anymore unless you can find a keen enthusiast willing to pay more, cars are like houses, they are worth what people are prepared to pay.
As an example, a stunning Z4 sport on nice 18's with all the bits only done 35k on a late 53 place has just gone for £8010 on ebay, great car, infact gutted I missed the bid (cant get the dealer out my head lol) but that gives you a taste of the current values, I only paid £8k for mine and thats a 2004 with 65k on the clock, spotless although admittedly I need some nice wheels haha but thats all (£500 quid with tyres)and has full BMWSH, heated seats etc
Good luck with your sale, hope that helped, someone will get a really nice car looked after well by the pics!
