Talking Cars: Our experts discuss roadsters and the latest test cars, plus answer reader questions

In episode four of "Talking Cars with Consumer Reports," our automotive experts discuss their picks among recently tested German roadsters, truck reliability, and the latest cars purchased for testing.

Once again, this podcast was recorded at our Connecticut Auto Test Center, within our large photo building. Senior Auto Engineers Gabe Shenhar and Tom Mutchler are joined by Managing Editor Jon Linkov for a candid, good-humored chat.

Clearly, opinions are divided on the drop-tops featured in our recent report, "Cars for the open road." But among the Audi TT, BMW Z4, Mercedes-Benz SLK, and Porsche Boxster, there seems to be consensus on the Porsche as the most desirable model.

The guys also discuss Ford EcoBoost reliability, small SUV diesels, and new arrivals at the track that count the Jaguar XF, Honda Accord Crosstour, and Hyundai Santa Fe three-row SUV.

Gabe takes reader heat for his blog about the disappointing Acura RLX, giving him a chance to talk about what true luxury is. Hint: Using the word "luxury" 14 times in an advertisement doesn't count.

Then Tom and Jon nearly come to blows over whether they'd buy a BMW 3 Series with a diesel or not.
