Today I am mostly wanting......

I like those alloys but would want them repainted the original silver. The "paedo shoe grey" leather interior is where it primarily falls down for me.

I don't want it as I have one very similar but this looks like a nice, well-price and well-specified example and I spy an MPerformance exhaust too:

 Nice interior colour combination. 

Yes but there’s a substantial difference between £23k and £30k, and this one has the advantage of considerably cheaper road tax.

Still lovely to look at too. Its the running costs that keep the price in check I guess. And odd that a 612, which I never liked the look of is still around 65K

I can't see the mileage on that?

Thanks.
The price of all 3/4 series often strikes me as odd as there are cars at 3 years old that are only slightly cheaper than 6 month old versions that are ostensibly the same.
However there are potentially huge spec differences and I think that plays a large part, e.g. a newer car with 18" alloys is much closer in price to an older one with the 19s.
6 - 12 month old cars that seem like a bargain can often be hair shirt - the number of 335ds on the market without heated seats, for example, is quite astonishing

A cost option on the 3 but standard on the 4 Series! A 4 is a very versatile car with the rear seats folded down. However if you need it for carrying things like fridges and washing machines then a 3 Touring is the only option.

It's the exact same interior combination that I have in my car - Saddle Dakota leather with Anthracite Fineline wood trim. The leather was no-cost and the wood trim was a £100 option. I steered clear of the various Individual options as they added 3-4 months to the delivery time meaning I risked not getting it before the tax changes kicked in, plus they add nothing to the GFV so have a pretty inflationary effect on the monthly PCP payments.

Money no object, I'd have had it painted individual Oxford Green II, with the full leather interior (including dash) in individual Cohiba Brown, and had either the maple or auburn individual wood trim. But that's over £6k's worth of options.

Yes they did.

This one, sat on Enzo alloys, looks spot-on. Has aged so very well:

Very nice indeed.

I have a friend who bought a 2007 M3 about 2 years after I bought my 335D in Dec 2006 and he still has it. However he had a fairly major engine/clutch/suspension rebuild at 80K miles, last year and was complaining that there was something else that was going to need done this year which he thought would be about £2K. After his £6K+ bill from last year this is the first time he has considered getting rid of it!

Some nice stuff there. The E9X V8 M3's are one I keep a close eye on - a bit "standard 3 series" inside, weak brakes, but..... that engine and handling! I was lucky to drive one at Bedford Autodrome and the engine is a strong memory from the day.

That Ferrari - like most of them these days - I can't get excited about as they are going for so much more now than a few years ago. I fondly recall good 308's being sub £20k, 328's 20-30, manual 360's and 355's £30-40k (less for some 360's). 456's and 550's were a total bargain as well, not that long ago. The current prices make it hard to buy them as a car to use. Like NSX's, and many older Lambos, their interest for me has gone for that reason.

Some Maseratis still seem great value, and I have a real soft spot for E34 M5's but I suspect they are well into money pit territory now... Another real-world one is the E46 M3, not one of the special editions - and like the E90 I'd consider a convertible as a toy. There is a lovely deep purple/blue E46 M3 cab a few doors down that I want every time I walk  past it, having been thoroughly converted as to the joys of open top motoring by our 1 series. 

I expect his is well maintained though, I was more thinking of buying one at 12 years old with 120k miles on the clock and possibly some iffy service history.

I think the 4 door has the most stealth look though and I can put up with a 3 series interior when I'll be busy looking out of the side glass half the time
