Both the models need to be serviced annually but the CDL being a diesel engine requires annual service that is costlier by $100. The life of a diesel engine is typically longer – hence the residual value of a 10 year old CDL is estimated to be $1600 higher than the Lexus. Assume (i) the average cost of premium gasolene to be $3.00 per gallon (ii) the average cost
