Nudged a car no details exchanged can they still claim against me?

Today I went into the back of someone's car whilst driving. The damage is minuscule where I have a small scratch on my bumper and they looked to have a similar scratch on there's nothing major. The guy leant out of his window and asked what happened there I apologised and asked if he was okay he nodded and drove off. I was more than happy to pull over and sort our details etc or sort damages with some cash but he just drove off without any questions. His car was a 03 plate ford so I can only presume due to the low amount of contact from car to car he was not fussed about damage. He didn't even get out to look at his car. I took his reg just increase and drove home. I'm wondering that if he wants to make a claim now how will he do it and will he be able to make it look a lot worse than it actually was etc as I can only presume he would have taken my reg also. Or should I not worry about this as he drove off himself without any questions etc?

Tranny replacement, 76 ford, what to get?

I'm considering a new tranny in my truck. It has a np435 in it and I want something that will put the power down better. It absolutely has to be a manual though. Suggestions.

Is it cheaper to buy a car that needs work? Read more?

I want either a 1967 chevy impala or a 1972 ford pick up. Would it be cheaper to buy a car that needs some work or a car that doesn't need any work? My moms friend is a mechanic and he would do work for me cheaper than if i went to a regular mechanic and got work done.

Speed pulse wire location?

Today i had to take the stereo out in my Ford Galaxy 2002. Anyway, as i done it the speed pulse wire (thin purple wire) came away from the yellow plug and now i don't know where it goes. As a result my cruise control has stopped working and i have no Automatic Volume Control displaying on the stereo when i scroll through. Does anyone know what pin the damn wire is supposed to be connected to please. Explain in idiots terms:-)

If A Car From 1940 Is Modified To To Use Today's Gas Will It Lower The Value Of The Car?

This is a 1938 Ford Eifel I believe from someone's Flickr account.
I asked a question about it being able to use gas from today's pumps and I got some great answers.
I don't know much about cars other than driving them and collecting pics of them so when a user said it would have to be modified to make it work another question popped up in my head.
When cars are rebuilt to classic status do you lose some of the collection by modifying it?
I know sometimes a part that can't be bought has to be made so does it detract from the value of it's antiquity.
If that's a silly use of the word I apologize but I do like asking questions so bear with me.
Thanks and thumbs up to all who answer… Just give me time to get back and read the answers. Added (1). I meant that to read:

Why hasn't Ford, GMC, Chevy etc. Make their van/box truck models with standard transmission?

Why do they stick these garbage automatic transmissions in their trucks/vans? I know this is farfetched but is it even possible to find a 5/6 speed manual transmission on a ford Econoline? GMC 2500/3500 etc. I guess the biggest reason they do this, is so they can make money once these things go toast. Which they constantly do. Why is their no petition in the USA that would tell these dealers to make more standard transmission cars like in Europe? In Europe even the Sprinter vans are manual, why do we not have this option?!
