I had a chat with an American a few days, and in his conversation, his "r" sound was so strong even in "car". In British English, if I am right, "r" sound isn't as strong as American like in saying "car" or "player
", the "r" sound in like "car" is often omitted.

Am I right?

Thanks in advance
Yes, the rhotic (strong 'r') pronunciation is characteristic of midwest AmE.
victorycountry, may be you could use "as in" rather than "in like".
