I don't reckon there's any issue. Don't worry. Your car is definitely a sleeper and sweet as! No one would expect what's under the bonnet and the funniest thing of all is that most of the police won't even know it's not stock because it's so clean and understated, especially if they're police of the female variety. Hah hah. My poor mate in Sydney got defected the other day in his corolla that's only done 39,000km. The stupid woman tried to fine him because she said she didn't believe he hadn't wound the clock back. It made me so mad but she did make herself look like a numnut. His cars cleaner than brand new. I've attached a pic..
Sooo, back to the point, your car is an awesome sleeper and the pure definition of the word. :laff:
