You're referring to the three customs exits at Heathrow Airport:

Blue is for arrivals from the EU with nothing to declare. People who can use this queue will see a green stripe around their luggage tag. Yes, this is slightly confusing.

Green is for arrivals outside the EU with nothing to declare.

These are based on the country where your air journey originated.

Red is for arrivals from anywhere who need to make a customs declaration.

Taken from Heathrow Airport: UK Customs processes at Heathrow

The UK has significantly different procedures for admitting people from the EU and from outside the EU. Since Heathrow has the largest amount of international air traffic of any airport in the world, it's important to not make people wait any longer than necessary. Separating them here helps keep the queues moving faster.

Heathrow Customs - "Arrivals from the EU" exit
One of my concerns before purchasing a car is how expensive repairs are going to be down the road. For example my car up until recently was a Volvo 850, and the air conditioner didn't work in it; the cost of getting it fixed was significantly higher than other cars because of the way the A/C unit is installed in the car, so I went on without air conditioning. Another example is the service light in the car - while the car had a standard OBD-II port which could read error messages, it required a special Volvo reader to reset the service light.

I know a lot of generalizations can be made about one make versus another, but those are obviously not allowed on this site (in fact, I hope this question is allowed at all...) - so that's not what I'm looking for. And I know there is a wide range of problems a car can encounter, and many of them are universal - replacing tires, for (a bad) example.

So, just like I can go to KBB and look up the recommended price of a car, is there someplace I can go to look up a make &amp; model of a car and see what proprietary, extra-expensive parts are in the car? Something that, for example, I could have put in the Volvo 850 and it would have told me about those above-mentioned peculiarities alongside undoubtedly a number of other proprietary bits that I didn't have problems with.
