You know the whole warranty thing bugs me.I am self employed in the HVAC business.If I go to your house and put in a brand new 93% effecient gas furnace and charge you $1100,I "clear"about $300.After business expenses (truck payment,misc supplies,insurance....)I usually clear about $100-$150 a day.BUT WE GIVE A 5 YEAR WARRANTY ON WORKMANSHIP.Our supplier gives a 5 yr,10 yr or even lifetime equipment warranty,depending on which model you buy.Now,here it is 2 a.m.,20 degrees below zero and you call me because your heat is off.You know what happens?I get out of bed and fix it! But when I spend $10,000 on my motor and it craps out on me in the quarter finals,costing me a gauranteed win,ANY engine builder will just shrug their shoulders and walk away with a fist full of your money. :evil:
