Rover 75 specifications

[Al75]

I've only recently joined the Rover 75 club. I had a 2005 diesel connie 10 years ago and loved the car. I did almost 150,000 in it, with very few problems before I let it go. It was the best car I had owned. Now retired I decided to get another as a toy to cherish. The car I've bought is another 2005 low mileage diesel connie. What I've found odd, is the difference in specs. My new car doesn't have chrome mirror covers or wood steering wheel and different wheels. Having said that, my new one has cruise control and power fold mirrors, which my old car didn't have. The most surprising thing is while driving my new car Ive realised my reversing sensors weren't going off whilst reversing. On closer inspection I found there wasn't any sensors fitted. Never noticed when I bought it. It set me wondering, in 2005 at the very end of Rover production, did they just make do and fit the parts they had in stock? I've now fitted chrome mirrors covers and a wooden steering wheel but need to fit reversing sensors. Has anyone any advice on fitting them.
Thanks for reading my ramble
