there are the same inelegant cars hed dodged when suicidally jay-trotting their avenues in 1951 : stolid peugeot 203s , bug-like renault quatre chevaux , a panhard dyna , gangsterish low-slung black citron tractions , plenty of gray dinky-toy deux chevaux , like garbage-cans on wheels , banged-up pre-war renault juvas and rosalies .
