Why would there be added wear
if, instead of sitting idling at 800-1200RPM, the engine and transmission were operated below 2500 RPM as you drive for the first few miles?
My Boxster now never goes out on cold days but when it did, it was a daily driver and took off slowly as soon as the seat belt was buckled which means maybe 15 seconds after start. The only time I ever idle to warm the cars I own are in snow, ice or fogged windows conditions where it is a matter of safety.
